Composite drive structure

The invention relates to a driving device, in particular to a composite driving device which can be applied to a special slot-shaped narrow space.

According to the wrench, the wrench is an indispensable and important tool for today's industrial development. It can be divided into fixed wrench and adjustable wrench. The typical fixed wrench is composed of a long flat handle. There is a wrench head, which uses the principle of lever to pull the screw-solid workpiece to achieve the effect of tightening or unscrewing, and it is necessary to assemble and assemble components of various industries by screwing the fastener; such a conventional fixed wrench once the handle is gripped There is other structure blocking in the radius of rotation, the fixed wrench can not continue to provide operation, the wrench must be detached and combined from another feasible angle before it can be used again, and the repeated combination and disengagement will Causes inconvenience and troubles in use.

Therefore, a manufacturer has developed a compound wrench embedded with a ratchet sleeve, which can generate a one-way ratchet by a ratchet sleeve, and pulls the screwed workpiece in a reciprocating manner. To achieve the effect of tightening or loosening, it will not be blocked by other structures within the radius of rotation of the handle, that is, the composite wrench and the locking workpiece need to be repeatedly combined and detached to improve the convenience of use, and more Efficient.

However, this kind of conventional compound wrench, the handle still can not make a circle in a small space The movement can only rely on the ratchet structure to reciprocate the handle in a certain angle range, and the screwing workpiece can be tightened or loosened. It is not suitable for the slot-shaped narrow space surrounded by other structures. The need to improve.

The present inventors have in view of the conventional composite wrench, which cannot be applied to a narrow space of a trough shape, so that the use is considerably limited, and the practicality and convenience are not good, so that the idea of creation and creation is discussed and tested by many parties. After the sample test, and the multiple corrections and improvements, the present invention was introduced.

The invention provides a composite driving device structure, comprising: a handle, a movable head and a handle bar, wherein the handle is an elongated body, one end is provided with a fixed head with a first set of holes, and the other end is provided with a fixed head The pivoting portion pivotally engages the movable head, so that the movable head can swing and adjust the angle. The movable head is provided with an operation hole group, and a ratchet wheel capable of generating a one-way ratchet is provided. The ratchet wheel is provided with a second sleeve hole. The rod is a rod-shaped body, and one end is provided with a plug portion, and the plug portion can be inserted into the turning hole of the grip fixing head, and the handle rod forms an angle with the grip.

The main purpose of the present invention is to use the first sleeve hole of the fixing head or the second sleeve hole of the movable head to fit on the screw-solid workpiece, and the screw-solid workpiece is pulled by the handle. In addition to the effect of tightening or unscrewing, there is a narrow groove-like space surrounded by other structures, and the handlebar is connected to the fixed head of the handle, and the handle and the movable head are pulled by the handlebar. Turn to achieve the effect of tightening or loosening, and the practicality and ease of use are improved.
